Falls are the leading cause of nonfatal injuries in the United States and the second leading cause of all unintentional injury deaths. Each year fractures of the hip account for about 200,000 hospitalizations among the elderly and falls are contributing factors in 40 percent of admissions to nursing homes. About 30 percent of community-dwelling elderly fall each year, with about 10 percent seeking emergency medical help for a fall injury. Data from CDC-funded study to assess falls among the elderly (SAFE) suggest that as many as 41 percent of elderly patients fall at home in the year following discharge from hospitalization due in part to deconditioning associated with inactivity.
